theo wants to put a dinosaur border around the perimeter of his room. How many rolls of border must he buy if each one covers 10 ft?

What is the perimeter of his room?

theo's bedroom measures 12 3/4 ft by 9 2/3 ft.

add up each side..12 3/4 + 12 3/4 + 9 2/3 + 9 2/3=?
Then divide it by 10
Round UP to the nearest whole number
